    Such a beautiful explanation. For guy like me with no spatial imagination this video is a gem.

    This is what years of mathematics has come full circle to, the application to the third dimension. Phenomenal explanation!

    Amazing explanation. Khan Academy is alright at teaching people arithmetically (at least in physics), but they’re sure as heck great at explaining concepts.
    Thank you to whomever had the idea for this video, it really helped.

  • @LodeanNick
    @LodeanNick 4 ปีที่แล้ว

    Isn't volume = double integration? i don't get why here you use only 1 integration, the result you found is the area isn't?

    how about sir if my concern is only the equation that describes the cross sectional area at x = 0 to x = 2 ??
    how to find that equation?
